1268 mountain eruct form that has the same size, an area of more than 50 square kilometers (20 square miles), geological formation is very unusual, called Chocolate Hills, is located in Bohol, Philippines. There are several hypotheses about the formation of the hills.
The hills include simple limestone weathering, sub-sea volcanism, the uplift of the seafloor and a new theory which states that it is an active volcano that destroyed the ancient, then spit a large rock and then covered with limestone and then pushed out of the base sea.
2. Wave Rock (Australia)
The Wave Rock is a natural rock formation located in western Australia. As the name suggests this stone shaped like a tall breaking ocean wave. The extent covers several hectares; Wave Rock has a height of about 15 meters and a length of about 110 meters.
One aspect of Wave Rock rarely shown in the photo is the retaining wall about half a stone. This follows the contours and allows rainwater to be collected in a dam. It was built in 1951 by the Department of Public Works.
3. Hell Gate (Uzbekistan)
Called by locals The Door to Hell, this place in Uzbekistan is situated near the small town of Drava When geologists drilling for gas, 35 years ago, they suddenly found an underground cavern that was so big.
No one dared to go there because the cavern was filled with gas, so they ignited it so that no poisonous gas could come out of the hole, and since then, has been burned. Nobody knows how many tons of excellent gas has been burned for many years, but it seems to be infinite.
4. Gyant Causeway (Ireland)
Area of about 40,000 basalt columns each other, which results Causeway Giant an ancient volcanic eruption. It is in the north-east coast of Northern Ireland, most of the hexagonal-shaped columns, although there are also rectangular, pentagon, heptagon and octagon.
The highest about 12 meters (36 feet) heigh, and the hardened lava in the cliffs is 28 meters thick in some places. In a 2005 poll of Radio Times readers, the causeway was named as the fourth greatest natural wonder in the United Kingdom.
5. Blue Lake Cave (Brazil)
Mato Grosso do Sul region in Brazil (and especially the quiet town of Bonito) offers many amazing underground lakes: "Gruta do Lago Azul".

Richat structures called - or Eye Sahara - formation
was originally thought to be caused
by a meteorite impact but now geologists
believe is a product of the removal and
erosion. The cause of a circular shape is still a mystery until now.
7. Crystal Cave of the Giants (Mexico)
Found deep inside a mine in southern Chihuahua Mexico, these crystals formed in a natural cave totally enclosed in bedrock. The caves were full of spectacular crystals as tall as pine trees, and in some cases the larger the circle, their colors like gold and silver are translucent and has exceptional shape.
Crystal Cave of Giants found in the body of the same limestone. Ore of silver-zinc-lead mines exploited by the body and may be dissolved by the same hydrothermal fluids that deposited the metals with the gypsum being crystallized during the reduced mineralization.
8. Great Blue Hole (Belize)Part of the Lighthouse Reef System, The Great Blue Hole is located approximately 60 miles from outside the mainland of Belize City. A large almost perfectly circular hole approximately one quarter of a mile (0.4 km) across, it's one of the most shocking dive sites to be found anywhere on earth.
Inside this hole, the water is 480 feet (145 m) deep and it is the depth of water which gives the deep blue color that causes such structures throughout the world known as "blue holes."
9. Antelope Canyon (Arizona - USA)
The most frequently visited and photographed canyon in the American Southwest, the Antelope Canyon is located on Navajo land near Page, Arizona.
This canyon includes two separate, photogenic slot canyon sections, referred to individually as Upper Antelope Canyon - or "Crack" - and Lower Antelope Canyon - or "corkscrew."
Navajo name for Upper Antelope Canyon is Tse bighanilini ', which means "the place where water runs through rocks." Antelope Canyon is lower Hasdestwazi, or "spiral rock arches." Both are located in the Navajo Nation Chapter Lechee.
10. The Wave (between Arizona and Utah - USA)
A pretty red-rock on the border of Arizona and Utah, The Wave is made of a sand dune 190-million years has been turned into stone.
